Is there anything like Apache’s mod\_dumpio? Any way to get a full  
running  
trace of request & responses, including the body data? Would such a  
thing be  
useful to anyone besides me?

does debug log ([A debugging log](http://nginx.org/en/docs/debugging_log.html)) suffice?

Just tried that out. Quite a nice dump, but I don’t see the body in the  
output.  
I’m tracing ActiveSync via a proxy, wanting to glean the WBXML in the  
body,  
kinda like using a proxy as a sniffer.

If I have to develop this, is the debug feature the right place?

I could see creating a filter module, maybe? Note that I also want to be  
able to capture & display POST data going toward the server.

Advice appreciate.

I would be quite interested in this as well. Debug log is great, but  
does  
not show full response bodies like mod\_dumpio does. Did you end up  
writing  
something?
